Exact measurements?

Hello,
I'm quite interested in buying the 660 Cafe Racer from Schott, but am skeptical about buying online. Unfortunately I live in Australia and I don't have a Schott retailer around that I can go to to try a few jackets on.
What are the exact measurements for the actual 660 Cafe Racer Jacket in a Large and Medium?
Mainly, Chest, Waist, Hip, Sleeve, Shoulder and Length sizing.
This would be really useful as I already have a solid leather jacket that fits me well, I would be able to run the measurements in comparison to that jacket and at least get a rough idea of how well it fits.
Any help would be greatly appreciated in this matter.
Thanks
